User Input and While Loops in Python
Below are some of the examples by which we can use while loops for user input in Python:
Taking User Input Using While Loop
In this example, the code initializes an empty list, prompts the user to enter numbers iteratively until the user inputs ‘done,’ converts each input to an integer, appends it to the list, and finally prints the resulting list of numbers.
Python3
# Initializing an empty list to store numbersnumber_list = []# Prompting the user to enter numberswhile True: num = input("Enter a number (or 'done' to finish): ") if num == 'done': break number_list.append(int(num))# Printing the list of numbersprint("List of numbers:", number_list) |
Output:
Enter a number (or 'done' to finish): 1
Enter a number (or 'done' to finish): 2
Enter a number (or 'done' to finish): 3
Enter a number (or 'done' to finish): 4
Enter a number (or 'done' to finish): done
List of numbers: [1, 2, 3, 4]
Get User Input in Loop using Python
In Python, for and while loops are used to iterate over a sequence of elements or to execute a block of code repeatedly. When it comes to user input, these loops can be used to prompt the user for input and process the input based on certain conditions. In this article, we will explore how to use for and while loops for user input in Python.
